cannot import name 'Mapping' from 'collections'

[brockp]

I just added the roomba plugin to my eisy setup running 6.0 and pg3,  it's not finding our roomba s9+

It doesn't start and discover doesn't appear to do anything. 

 

I can control it from the app just fine, looking in the logs there are a bunch of errors that look like python errors:

Hmm. This is not my plugin, but I recognize this error. The Mapping class is in collections.abc, not collections. And it's been that way since Python 3.3. I think Python 3.3-3.9 had an alias that allowed imports from collections, but that was removed in Python 3.10. But that was like 4 years ago. And udx has included Python 3.10 or 3.11 for most of that timeframe. So it doesn't make a lot of sense that it would just now be cropping up now. I guess it's possible that the Roomba plugin (or the roomba library it depends on) hasn't been updated in A LONG TIME.

I see the plugin is in a GitHub repo and it's free. The quick fix for you would be to ssh into your eisy or policy, navigate to the /var/polyglot/pg3/ns/0021b9026aaf_9/roomba.py file, and change

 from collections import Mapping

to

 from collections.abc import Mapping

using a text editor, like ee or vi. 

A better solution would be to fork the repository in GitHub, make the fix and make a pull request to Bob to merge it back in and upload a new version of the plugin. That way, it should work for anyone who needs it.
